BALL VALVE PRESSURE REGULATOR Russian patent published in 2023 - IPC F16K5/06 F16K1/02 F16K11/20 

FIELD: valve building.

SUBSTANCE: ball valve-pressure regulator comprises a body with an upper branch pipe, in which a cylindrical rod is installed, which is a shut-off and control element, as well as with inlet and outlet pipes providing an axial flow channel, in which a ball plug with a seat is installed. The stem is configured to control the pressure in the outlet pipe between the disc-shaped surface of the seat of the ball plug and the mating surface of the lower end of the stem. A balancing spring is installed on the rod, connected to the tuning element of the balancing spring. The body has a lower branch pipe, with a valve installed in it, with the help of a nut and a seal, to completely block the flow channel with a ball plug. The valve comprises a spindle, one end of which is placed in the outer lower groove of the ball plug configured for being acted on it by the spindle, and the valve handle is rigidly fixed at the other end of the spindle, with the help of a nut, to control the movement of the spindle. A cover is rigidly fixed on the upper branch pipe of the body, between which and the upper branch pipe a rubber seal is placed. The ball plug has at least inlet and outlet flow channels connected, in the open position of the valve, with the inlet and outlet pipes of the body, respectively.

EFFECT: improved performance characteristics.
